President Obama has given Shell the green light to drill for oil in the Arctic Ocean, but activists and politicians in Seattle are throwing up as many stop signs as they can as the drilling rig preps there for its journey north. It's the latest flashpoint in the growing international anti-fossil fuel movement.

There may be a counterintuitive explanation for the deep freeze that hit New England this winter: The rapidly warming Arctic is causing big disruptions in the jet stream, which carries weather across North America. Is this the worst winter you've experienced?

Everyone’s heard of the bombing of Pearl Harbor in Hawaii, but six months later, the Japanese also bombed Dutch Harbor in Alaska. Three days after that, they captured two remote islands far out on the Aleutian chain. It's a battle that's all but forgotten, but it's the subject of a new book.

A new study of blue whales in the eastern Pacific has found that the population of the behemoths there has bounced back to near pre-whaling levels. But other populations of blues elsewhere are not doing nearly as well.

The United States controls immense amounts of water, so why does most of the seafood you eat come from other countries? A new book looks at the many ways the American seafood industry is out whack — and how it might be fixed.

The discovery of two giant holes in the ground in far northern Russia is raising all kinds of speculation about their origin. No one yet knows for sure how they were formed, but a leading scientist is pointing to an ever-more usual suspect—climate change.

Adults in Switzerland could be in for a windfall, under a proposal set for a national referendum. The government would provide every adult $2,750 a month, every month, in what's known as a "basic income." One economist says it's not as whacky as it may seem to us.

Today's Geo Quiz takes us to Nebraska's Platte River where an estimated half a million Sandhill Cranes stop in his time of year along their annual migration route north. Alicia Hardin of Nebraska's Game and Parks Commission speaks with anchor David Baron.

Scientists studying the Arctic are predicting the ice cap will shrink to record levels this year, a condition many blame on human-caused climate change. That'd led some to conclude that before this decade is out, we could have a summer day or days where there's no Arctic ice cap at all.

The World's Daniel Grossman reports from Greenland on disturbing changes. A new report says ice in Greenland and other northern regions is melting far faster than predicted just a few years ago, with possibly serious consequences for global sea levels.

Deep beneath the frozen Arctic are deposits of methane. Lots of methane. And there's even more on the sea floor. As the environment warms, these deposits are being released into the atmosphere, presenting grave risks of runaway warming.
